RUBERT FULLERTON, OF DES M OINBlS IOWA.

PNEl JMAT IQ LoG-sAw. l y i citizen of the United States, residing in Des mechanical means for sawing down trees in a Moines, count of Polk, and State'of Iowa, have invente a new and useful Improvement in Pneumatic Log-Saws, of which the following is a specification.

The object of myinvention is to provide a forest, which may be easily and quickly manilpulated and. operated by two men and W ich will work with such rapidity that the largest and toughest trees may be felled in an exceedingly short length-of time.

A further object is to construct such a means in such a light and compact manner as to make it portable by the operators and to be adapted for use in sawing logs as well as in cutting timber.

A further object is to provide such a means in a simple, strong, durable and inexpensive construction.

My invention consists of certain details of construction thereinafter set forth pointed out in my claims and illustrated in the accompanying drawings in which Figure I shows a side elevation of my device, the chain belt s'aw bein removed and the central portion being bro en away; F ig. II shows a transverse section of the chain belt saw; Fig. III shows atransverse section of the framework I employ; Fig. IV shows a plan view of my device the chain belt saw bein removed and a part of the central portion being broken away; Fig. V shows a longitudinal sectional view one of the lates I em loy bein removed; Figs. VI, V-I VIII, I X, & X show detail'views of my device. The Fig. XII shows a planview of a portion of my device, the chain belt saw being shownin position on the track.

Referring to'the accompanying drawings the reference numeral 10 is used to indicate one of the side lates I employ in the con'-. struction of the ramework on which my improved saw is designed to operate and the numeral 11 indicates the other plate or companion late the two said plates being exactly simi ar in every respect and each being pro vided with concave ends for purposes herein-- after stated. Riveted between'said plates and extending above their upper edge surfaces for their entire len the is a metal bar 12 said bar bein provide with a centrally located lon itu inal ridge orraised 1portion 13 said raise portion having vertica -Specification of Letters Patent.

extend g'alon the entire len th of the bar 12 and designs to be emplo e as a track for purposes hereinafter state The numeral 14 indicates a like metal bar riveted between the said plates 10 and 11 at their under'e'dge. surfaces said bar being rovided on its outer longitudinal surface wit 1 a centrally located ridge or raised portion 15 exactly similar to the raised portion 13 and designed to be operated as a companion track therewith.

' Secured in an adjustable manner to one of the ends of the frame work described is a support frame 16 within which a gear or sprocket'wheel 17 is designed to be mounted the'frarne-work described. The shaft 18 on" which the gear wheel 17 is mounted is'de signed to be operated by a small en ine or compressed air machine 19 aflixed on the outside of the frame work.

The numeral 20 indicates a handle secured to the support frame 16. The numeral 21 indicates a support frame, secured to the other end of the frame before described, said sup ort-frame being similar in every respect to t e support frame 16 and adapted to support a gear or s rocket Wheel 22 designed to operate within-t e concaved end of the frame work and to be employed as an idler over which the chain belt as hereinafter described operates.

The numeral 22 indicates a handle secured to the support frame. The saw portion proper of my device, com risesa chain designed to travel on the trac s 13 and 15,co1nposed of a triple series of links 232 4-25 respectively. The links 23 are constructed with a tooth 26 on the forward portion of its upper surface and having its under surface curved downwardly at 27 and the links 24 are constructed with a downwardly curved under surface, 28 exactly similar to the under surface of the link 23 and having a'tooth 29 belt saw, all of the links -23 are arranged on one side thereof and all of the links 24 are ar- IIO 23 and 24 and the Ii width of the tracks 13 and 1,5, and the face of vice is then complete.

ranged on the other side thereof, the links 25 being designed to be laced between the links thus arranged are riveted to ether. By this combination all of the teet on one side of the phain belt saw are on the forward part of the links and all of the teeth on the other side are on the rear art of the links and the teeth on the links between the links just described assume a pbsition between the two. The rivet holes in the various links described are arranged in such'a manner as to provide for the downwardly projecting curved portion 27 and 28 on the links 23 and 24 extendi'n below the under surface or the links 25. T e width of the link 25 is by construction equal to the the tooth on this link is at ri ht angles to the sides thereof. The chain be t saW being thus formed is placed on the tracks 13 and 15 and over the gear or sprocket wheels 17 and 22, and adjusted and the mechanism of my de- In practical operation the ower being ap plied throu h the compressed air machine or engine 19 tile cutting chain belt is started in operation on the tracks 13 'and15 by means 0 the drive-wheel 17 and theo erators conveying said device by the hand cs 20 and 22 a preach a tree or lo to be sawed and-hold t e rapidly moving c ain against the same.
